Please don't spread the info that 6.5 hours are sufficient. If you sleep only that much for a week, that's like skipping one entire night of sleep. People do it all the time but it's killing you. 8 hours is the optimum for an adult human.

7-8h on average, but depends on your genes, for some people 6.5h can be enough, but it's true it's definitely not for most people :)
